An afternoon of protests ended in many arrests in the Hart Senate Office Building on Thursday as a group of mostly female protesters flooded the atrium of the work space to protest President Donald Trump’s immigration policies.

United States Capitol Police charged nearly 575 individuals with “unlawfully demonstrating,” according to a Capitol Police statement Thursday.

Several Democratic lawmakers including Sen. Tammy Duckworth of Illinois and Rep. Jamie Raskin of Maryland were in attendance, and Rep. Pramila Jayapal of Washington — an immigrant herself — was among those arrested.
